Sample: Wild-type, interphase COS-7 cell (ATCC CRL-1651)

Sample Description: Near isotropic FIB-SEM imaging of cultured, wild-type, interphase COS-7 cell (ATCC CRL-1651). Imaging acquisition reconstructed using Hess Lab software.

Protocol: High pressure freezing, freeze-substitution resin embedding with 2% OsO₄ 0.1% UA 3% H₂O in acetone; resin embedding in Eponate 12.

Contributions: Sample provided by Melanie Freeman (Infinimmune) and David Hoffman (10x Genomics), prepared for imaging by H. Amalia Pasolli (Rockefeller), imaging by C. Shan Xu (Yale), with post-processing by Gleb Shtengel and Harald Hess(HHMI/Janelia).
